Unhappy customer due to poor service

Telkom decided to incorrectly debit my account on the 15th monthly I pay my account on the 20th and today , Telkom decided to debit my account I call 4 times this morning the agents at Telkom disconnected my call and also routed me elsewhere were I listened to music until I dropped The management is not available to assist or advise what happened and why my account was debited early this is inconvenient as that my transportation money for the week Giving companies like Telkom debit check rights helps them to abuse their power as I now can not reverse this transaction
